A bag (1) is formed by overlaying a sheet (2) on a sheet (3) so that a main gas passage (7) and small chambers (8a to 8k) are formed between both the sheets (2) and (3) by connecting peripheral portions thereof. The main gas passage (7) extends from the lower end of a front-side portion (1F) of the bag (1) to the rear end of an upper-side portion (1U). First, gas from an inflator (30) inflates the main gas passage (7) in the shape of a linear bar so that bag (1) is spread like a curtain. Then the gas flows into the small chambers (8a to 8k) from the main gas passage (7) via gas inlets (12) to inflate each of the small chambers (8a to 8k). |
